Terracotta Bottle Olla Irrigation Pot | Large 1200ml

A large terracotta bottle olla for deep, water-wise irrigation

The large bottle olla is a sculptural and functional watering tool rooted in one of the oldest irrigation methods in the world. Buried in the soil and filled with water, the porous terracotta walls slowly release moisture directly into the root zone where plants need it most. Less evaporation, less surface watering and stronger, deeper root systems as a result. A quiet, effective solution for the Australian garden.

How ollas work

Bury the olla up to its narrow neck, fill with water and replace the lid. The unglazed terracotta clay releases water slowly and steadily into the surrounding soil through capillary action, drawn by the roots of nearby plants. The soil directly around the olla stays consistently moist while the surface remains dry. This eliminates the cycle of wet and dry that stresses plants between waterings.

In the Australian native garden, where deep, infrequent watering is the ideal and overhead watering can cause problems with disease-susceptible species, ollas offer a particularly well-suited alternative. Plants establish faster and develop more extensive root systems when moisture is delivered at depth rather than at the surface.

Low-maintenance and long-lasting

Once buried and filled, the olla works without intervention making it a reliable solution across busy weeks, holidays and the long dry stretches of the Australian summer. Each olla is made from natural red terracotta clay and fired at high temperatures for strength and durability. The removable lid keeps debris and insects out between refills. Every piece is unique and may show the natural variations in tone and texture.
